Eviation and Kokam announce all-electric aircraft battery supply deal worth >$1M

Eviation Aircraft, a global manufacturer of all-electric air mobility solutions, and Kokam, a leading battery manufacturer based in South Korea, have entered into a battery supply deal worth more than $1 million. Kokam batteries will be used to power Eviation’s all-electric Alice aircraft, set to fly by the end of this year.

Alice, which made its debut at the 52nd Paris Air Show in June 2017, leverages an IP portfolio that includes thermal management and autonomous landing, as well as distributed electric propulsion, a 900 kWh battery pack provided by Kokam, and advanced composite body frames capable of carrying up to 9 passengers on a single charge for 650 miles (1,047 miles).

Alice’s distributed propulsion system uses one main pusher propeller at the tail and two pusher propellers at the wingtips to reduce drag, create redundancy, and improve efficiency.


Kokam’s battery solutions feature a compact battery cell design, an industry-leading energy density of 260 Wh/kg and a long cycle life, making them optimized to achieve light, energy efficient solutions meeting the safety demands of an aircraft. While the company’s battery solutions have been used in aerial, ground, surface, and underwater drone applications for military, commercial, and industrial purposes, this deal with Eviation marks the first time they will be used in manned aerial flights of regional commuter aircrafts.

Eviation is seeking to make regional air travel emissions-free with a fully-electric aircraft design, built from the ground up to cut costs and improve efficiency on the busiest city-to-city transit routes, such as San Diego to Silicon Valley and Seoul to Beijing. Through 2019, Eviation will certify and commercialize its all-electric Alice aircraft, while partnering with leading industry suppliers, including Kokam, to bring its prototypes to scale and to the market.

Eviation is a member of NASA’s on-demand mobility program, and serves on the electric aviation committees of the General Aviation Manufacturers’ Association (GAMA) and the US Federal Aviation Administration (FAA).
